Bay Area: FBI joins search for killer of 13-year-old girl

FAIRFIELD, Calif.—Fairfield police say they're working with the FBI in the search for the killer of a 13-year-old girl whose body was found in a park last week.

Police released few new details during a press conference Wednesday, but did repeat their request for help from the public, especially anyone who may have seen Genelle Renee Conway-Allen Thursday afternoon.

The teen was reported missing around 5:45 p.m. Thursday by her guardian at the foster home in nearby Suisun City where she lived. Police say her naked body was found a little before 7 a.m. Friday by a passerby.

The manager of a market located near a surveillance camera that took a photo of Genelle shortly before she vanished told police that a girl matching her description was outside his store.

Ibrahim Mohammad told The San Francisco Chronicle that the girl said she was waiting for a ride when he asked.
